摘要
采用概率统计方法,对兰州 级阶地黄土的物理力学性质进行分析.根据该区黄土典型物性指标的离散程度对黄土抗剪强度、湿陷性的影响,推导出相应的回归方程,并判断回归方程的有效性.结果表明,对于兰州 级阶地黄土,液限是内聚力的重要影响因素,含水量、原始孔隙比和干容重是湿陷系数的重要影响因素.
The method of statistical analysis is used to examine mechanical properties of the loess soil. According to the influence of the shear strength and the collapsibility exposed by the physical properties, the regression equation is deduced, the degree of correlation is analyzed, and the availability is obtained. To the loess soil in the third level terrace, water content is an important factor influencing the cohesion while; water content, void ratio and dry unit weight are important for the coefficient of collapsibility.
